Abstract: JACKS FOR ELECTRICAL CONNECTIONS WITH TELEPHONE EQUIPMENT     Abstract of the Disclosure The present invention relates to a telephone jack for selectively connecting and disconnecting telephone station equipment to a telephone line.  The station equipment is connected to the jack by plugs which are complementary to the jack.  The jack is comprised of a housing which includes a cavity for accommodating complementary plugs of different sizes.  A plurality of connector contact springs are provided, positioned within the cavity for engaging the contacts of the complementary plugs.  A pair of switch contact springs is provided, one of which is biased against the other contact spring.  The biased contact spring is deflected away from the other contact spring and is responsive to the insertion, within the cavity, of a complementary plug of a first size.  The biased contact spring remains in engagement with the other contact spring upon the insertion in the opening of a complementary plug of a second size, the switch contact springs being respectively, electrically connected in parallel with individual connector contact springs.

Abstract: ABSTRACT OF THE DISCLOSURE:           A comminuted or particulated growth substrate is produced by extracting peat blocks from bog and drying these blocks to a moisture content of 10 to 30 %; the  blocks are thereafter compressed into a volume of 1/3 to 1/10 of their initial and the particulated growth substrate is prepared from the compressed blocks by cutting or frasing.  The method according to the invention enables one to prepare a filling material for pots which has the desired ideal physical properties for paper pots.  When using the product in a dry state for the filling of pots it flows easily even into a small pot.          After wetting, the product in the pot swells quickly, thus giving a tight filling.  The same filling technique may be used also for other pots and cultivation troughs.

Abstract: FACET TRACKING IN LASER SCANNING                   ABSTRACT OF THE DISCLOSURE         Method and apparatus for improving the effi-ciency of laser scanning systems using a multi-faceted rotating polygon as the scanner device.  In particular, an acousto-optic Bragg cell is utilized as an active optical element to both modulate and deflect an inci-dent laser beam so that the modulated beam is caused to follow one facet of the scanner during a complete scan and to shift to the adjacent facet for the following scan.   An active optical element modulates and deflects a beam of radiant energy in accordance with the information content of a drive signal applied thereto, and the beam is focused to a spot upon the surface of a medium that is sensitive to the radiant energy.  A scanning device with at least one reflective surface is positioned in the path of the beam and scans the spot across the medium by rotating the reflective surface a desired angle to impart the information content of the spot to the medium.  A start of scan signal is generated and, in response thereto and to the electrical signal that provides the drive signal, the drive signal causes the beam to track the reflective surface during rotation and trans-lation thereof during scan.

Abstract: COMBINED CYCLE ELECTRIC POWER GENERATING SYSTEM WITH         IMPROVEMENT                     Abstract of the Disclosure A combined cycle electric power generating system which drives two electric power generators at a constant speed.  It employs a gas turbine to drive one of the generators and a steam turbine to drive the other.  There is a combustor that supplies the gas to drive the gas turbine and there is an air compressor that feeds input air to mix with fuel into the combustor.  The com-pressor is driven by the gas turbine.  The ex-haust from the gas turbine delivers heat to make steam for the steam turbine.  And, there is means for throttling the inlet air to the com-pressor so that the whole system may be run at greatly reduced load without creating inefficient operation.     I

Abstract: ABSTRACT OF THE DISCLOSURE:            Process of directly reducing iron oxyde-containing materials to produce sponge iron in a rotary kiln by means of solid carbonaceous reducing agents having a high content of volatile combustible constituents, said kiln having a heating-up zone in which the solid charge is heated to approximately the reduction temperature, wherein oxygen-containing gases are injected at a controlled rate through shell pipes into the free kiln space and the charge is moved through the rotary kiln countercurrently to the flow of the kiln atmosphere. The process of the invention is characterized in that oxygen-containing gases are injected at controlled rates through said nozzle blocks into the charge disposed over nozzle blocks in that region of the heating-up zone which begins at the point where ignitable particles of the solid reducing agent first appear and terminates before the reducing zone and oxygen-containing gases are injected at a controlled rate through shell pipes into the free kiln space of the heating-up zone. The advantages afforded by the invention reside in that the length of the heating-up zone of the rotary kiln is greatly reduced and, as a result, either the throughput rate of given kiln is increased or a smaller kiln may be used for a given throughput rate.  In addition, the difference between the gas temperature and the bed temperature is minimized and the exhaust gas temperature is minimum too. The lower heat content per unit of volume reduces the danger of a formation of crusts and increases the durability of the refractory lining.

Abstract: VIDEO RECORDING DISK WITH INTERLACING OF DATA FOR FRAMES ON THE SAME TRACK                   ABSTRACT    A video recording disk is adapted to be rotated at a uniform angular velocity and to have bit positions of substantially equal length along a track, and the longer outer tracks are given more storage positions than the shorter inner tracks.  Variable numbers of frames are located on each track revolution, depending on the data capacity of the track.  Frames are divided into data units that correspond to a few horizontal lines, and frames on the same track are interlaced so that the data units of each frame are distributed evenly around the track revolution.          The associated record player has simplified data storage requirements, particularly for freeze frame display of the television picture and for playing disks that hold video information in a data compression format.

Abstract: ABSTRACT      In a heat accumulator, a heat exchange  medium is passed through a heat accumulator medium.  The heat exchange medium can either be heated or cooled external to the heat accumulator medium.  If it is heated, it gives up its heat to the accumulator medium, and in doing so changes from the gaseous to the liquid state. If it is cooled, it absorbs heat from the accumulator medium, and in doing so changes from the liquid to the gaseous state.  In both cases, the opposite change of state is brought about by the heating or cooling external to the heat accumulator medium.
